You may want to check how the Paho client is initialized. If
autoreconnect=false, we've experienced similar issues(inexplicable mass message
loss). It should be true, and either clean session = false, or you must
initialize a custom
{code:java}
MqttCallbackExtended{code}
and keep track of your subscriptions, so that you can auto-reestablish on
{code:java}
connectComplete -> reconnect==true{code}

> Key: ARTEMIS-4296
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4296
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.28.0
> Reporter: Daniel Martin
> Priority: Blocker
>
> Please, see [https://github.com/apache/activemq-artemis/pull/4492]:
> {quote}In the following test, a broker client sends 1000 messages which are
> expected to be received by a second client, which in turn replies to every
> message with new ones (thus being labeled "server"). _It fails every time_ –
> the broker just seems to get stuck and stop sending messages at a given
> moment.
> In case it is useful, when lowering the number of messages sent to 100, you
> should see that the test sometimes passes.
> I have been running the tests with:
> {code:java}
> $ cd tests/integration-tests
> $ mvn verify -DskipIntegrationTests=false
> -Dtest="MQTT5Test#testRequestResponseMessages*"{code}
> I created this test to reproduce a slightly more complicated case I am
> dealing with at the moment where, in a production setting, messages are
> getting lost left and right and I haven't got a clue why.
